It's funny, because I see it the other way around: I drink less often than I used to, and now I need less alcohol to feel the effects, and I find it cool that way :).
Experiencing this too... I used to get like 225cl of 6% alcohol beer on fridays. Now I've reduced and 75cl gives me the same pleasure and effect. Less money spent, less damage on the body, feeling better in the morning...
There's no way I will stop drinking completely, I like beer too much. But reducing has really no downsides at all.
